村田GCM1555C1H391JA16D是一款通用型多层陶瓷贴片电容(MLCC),隶属于村田经典GCM系列,专为高密度、高稳定电子电路设计。以下从产品身份、核心性能、应用场景等维度展开详细概述。
该型号的编码逻辑可清晰对应核心参数:
该电容聚焦“精密稳定+高频适配”,关键参数特点明确:
390pF±5%的容值精度在MLCC中属于高稳定级别。不同于X7R等温度系数较大的介质,C0G的容值随温度、电压变化极小,可确保电路匹配、滤波等功能的一致性。例如在蓝牙4.0模块的射频匹配网络中,其容值偏差不会因环境温度变化(-55℃~125℃)导致信号反射或失真。
50V直流额定电压,满足绝大多数消费电子、通信设备的中低压需求(典型工作电压多在3.3V~24V范围内),可有效避免过压击穿风险,同时无需过度降额设计,节省电路空间。
C0G(NP0)是MLCC中温度稳定性最优的介质类型,温度系数≤±30ppm/℃(行业标准),且无直流偏置效应(容值不随施加电压变化)。此外,其损耗角正切(DF)极低(典型值<0.1% at 1kHz),高频响应优异,适合1GHz以上的射频电路。
村田的MLCC工艺是性能可靠的核心支撑:
C0G介质由钛酸钡等陶瓷材料调配而成,无老化现象(容值长期使用不衰减),适合对长期稳定性要求高的工业控制、精密仪器等场景。
0402小封装采用超薄多层陶瓷叠层技术,电极层均匀分布,减少寄生电感与电阻,提升高频性能。同时,村田的贴片端电极采用三层结构(镍+铜+锡),焊接兼容性好,可通过回流焊、波峰焊等工艺,适配自动化组装线。
该电容因“小体积+高稳定+高频适配”,广泛应用于以下领域:
村田GCM系列符合全球主流环保与质量标准:
综上,村田GCM1555C1H391JA16D是一款高性价比的精密MLCC,在小体积、高频、稳定需求的电路中具有不可替代的优势,是通信、消费电子、工业控制等领域的主流选型之一。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
